摘要

A series of novel chiral C₂-symmetric bis (oxazoline) ligands have been synthesized. The copper and magnesium complexes, prepared in situ from copper (II)-triflate or magnesium triflate with the new enantiopure oxazoline ligands, were evaluated as chiral catalysts in the enantioselective Diels-Alder reaction of cyclopentadiene with N-crotenoyl-oxazolidin-2-one. Primary results showed that diastereoselectivity up to 94% and enantioselectivity up to 68% ee for endo products were observed respectively with these ligands.
